A European team of physicists has demonstrated a device that can
teleport quantum information to a solid-state quantum memory over
telecom fibre, a crucial capability for any future quantum internet.

Quantum teleportation is the ability to transmit from one location to
another without travelling through the space in between. Matter itself
doesn’t make this journey, only the information that describes it. This
is transmitted to a new body that takes on the identity of the original.

But while science fiction fans have focused on body involved, quantum
physicists are more interested in the information. For them,
teleportation is the enabling technology behind a new generation of
information processing technologies including a quantum internet that
allows information to be transmitted with perfect security.
